Abstract
The goal of this project was to assess how GoTriangle might most effectively implement
battery electric vehicle (BEV) buses by analyzing possible environmental and social
factors and providing recommendations for BEV bus implementation to maximize operating
efficiency and social good. The core questions that drove the analyses were (1) whether
GoTriangle is a good candidate for BEV bus implementation and (2) how GoTriangle might
best implement BEV buses. Four analytical components were chosen to address the goals
of the project based on participatory feedback from project clients: (1) analysis
of potential grid impacts of charging the electric fleet, (2) comparisons between
BEV bus well-to-wheel emissions and conventional diesel bus well-to-wheel emissions,
(3) suitability analysis of route legs – the most granular transportation planning
units used by GoTriangle, and (4) spatial analysis of emissions to address environmental
health and environmental justice concerns. This report found that GoTriangle is likely
a good candidate for BEV bus implementation. Increased demand to the grid would likely
be negligible from a transmission point-of-view. In maximum fuel-economy scenarios
with an energy mix based upon Duke Energy’s integrated resource plan, it appeared
that BEV buses would contribute less emissions in every category when compared to
diesel buses. Though, it should be said that comparatively larger contributions of
some air pollutants were observed in minimum fuel-economy scenarios. Many bus route
legs – the smallest planning units used in route optimization – appeared to be good
candidates for implementation based on physical characteristics known to be associated
with energy consumption. Route legs located near and around Raleigh were found to
be some of the most optimal options based on their physical properties and comparatively
greater potential to mitigate human exposure to criteria pollutants.
